STRAIGHTCURVE Pre-curved Rings

STRAIGHTCURVE Pre-curved Rings are ready-to-install circular steel planter rings designed to create beautiful, defined planting zones around trees, feature plants, and garden specimens. Pre-formed into a perfect circle straight out of the box, these rings eliminate the guesswork of shaping and deliver a clean, professional result with minimal effort - ideal for both homeowners and landscapers.

Available in three heights - 240mm, 400mm, and 560mm - each ring suits a different planting application. The 240mm ring is perfect for low-growing ornamentals, ground covers, and decorative mulch borders. The 400mm height provides excellent soil depth for shrubs, native plants, and feature specimens, while the 560mm ring offers a bold, raised planter ideal for small trees, deep-rooted plants, and statement garden features.

Crafted from genuine Weathering Steel (Corten), these rings develop a rich, natural rust patina over time that stabilises and protects the steel - no painting or sealing required. The warm, earthy tones complement Australian native gardens, contemporary landscapes, and coastal settings beautifully, blending seamlessly with pebbles, mulch, and natural stone.

Installation is straightforward: simply position the ring, secure the joining tab, and fill with quality soil or growing media. The rigid pre-curved form holds its shape under soil pressure, making it a durable long-term solution for garden edging and tree surrounds.
